CAR-COUPLING.

SPECIFICATION formingpart of Letters Patent'No 377,541, dated February 7, 1888. Application filed November 12, 1887. Serial No. 254,963. (No model.)

a means of coupling without passing or standing between the cars, and also to provide a means for automatically raising the link in position to enter the draw-head.

The invention consists in the construction and combination of the severalparts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of opposing drawheads having my improvement applied. Fig. 2 is a plan view of the same, and Fig. 3 is a front elevation of a single draw-head.

In carrying out the invention, to one side of the ordinary draw-bar, A, about centrally the same, a bar, B, is longitudinally and rigidly attached, which bar is made to project beyond the face of the draw-head, terminating in a preferably flat head, b. 'In the same position upon the draw head, at the opposite end of the car, a substantially similar bar, D, is held to slide, the attachment being formed by passing the bar D, which for convenience I designate a bumper'bar, through hangers O O.

The hanger Ois secured to the draw-head and the hanger O, in alignment with its mate, to a convenienttimber of the car, as illustrated in Fig. l.

The bumper-bar D is madeto projectbeyond the draw head a greater distance than the bumpenbar B, and is provided at its outer end with a head, d, similar in shape to that integral with the bar B. The inner end of the bumper bar D is reduced, as shown at 01', whereby a shoulder, d",is produced,and around said reduced portionv a spring, d is placed, adapted'to have abearing, respectively, against the hanger O and the shoulder d To the rear of the hanger G a dog, E, is pivoted, adapted to hang normally perpendicularly downward,

pivoted to the draw-head, which lifting-bar isv provided with a pin-like projection, f, integral .with the rear pivotal end, adapted, when the lifting-bar is in its normal position, to extend vertically upward at right angles to the body in position for engagement by the dog E.

The body of the lifting-bar F extends par allel with the side of the draw-head at an inclination downward beyond the month thereof, at which point the outer extremityof the said bar F is bent at right angles to the body and'made to project transversely the face of the draw-head below and in advanceof the lower edge, as shown at f, Fig. 3.

- A pin-bar, H,'is pivoted at the side of the draw-head supporting the bumper-barD above the said bar, the lower end of which 'pinbar H is projected downward behind the bumperbar D and turned upward at right angles below the bumper-bar, producing a crank-arm, h, in alignment with the crank-arm or projection upon the inner end of the lifting-bar when the latter is in its normal position.

The body of the pin-bar H extends horizontally beyond the end of the car, and thenvertically upward a distance equal to the height of the head of the coupling-pin. When drawn upward out of the draw-head, the said body is from this point carried horizontally above the draw-head and transversely over the top of the draw-head in substantial alignment with the pin-aperture in the draw-head, and provided with a semicircular recess, h, in the extremity to receive the pin.

Upon the opposite side of the draw-head and in alignment with the rocking pin-bar H a second and substantially similar-shaped bar, H, is rigidly secured to the said draw-head, the extremity of the upper member being'made to engage the corresponding member of bar H, having alike aperture, h", produced therein.

The two bars Hand H are connected above the draw-head by a spring, 7L3, whereby when separated they will automatically return to. an engagement.

The coupling-pin N is adapted, when out of 100 engagement with the link or when the cars are uncoupled, to be held between the bars H and H, as shown in Figs. 1 and 3; and from the headpf the pin, and integral therewith, a conical guide-rod, G, is projected upward and connected with a chain or in other suitable manner with an arm, m, extending outward from and secured at rightangles to a revoluble shaft, M, journaled transversely the end of the car above the sill, which shai'tis rotated or reciprocated by crank-arms M at the ends or by any other device which in practice may be found desirable.

In operation, when opposing draw-heads are to be coupled, the bumper-bar B, coming in contact with the opposing bumper D, will force the latter back, causing the pawl E to strike the crank-arm f and bring the lifting-bar in engagement with the link, whereby the latter is positioned to properly enter the link-opening. In the continued rearward motion of the bumper D the lifting-bar is released and'permitted to return to its normal position, the dog E caused to engage the crank-arm h of the pinbar H and force the said pin-bar laterally out of contact with the fixed pin-bar H, whereby the pin Nis released,which, dropping in the drawhead, passes through the link, completing the coupling. The spring it automatically draws the two bars H and H toward each other and in contact with the conical guide-rod G when it is desired to uncouple, and to that end the shaft is turned, so the guide-bar will open the pin-bars H and H to receive and retain the pin.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isv 1. The combination, with a draw-head, a spring-actuated bumper-bar held to slide at one side of the draw-head, and a dog pivoted upon said bar, of a lift-bar pivoted below said bumper, provided with a crank-arm at one end adapted to engage said dog, and a member in-' tegral with the other end projecting transversely in front of the draw-head, substantially as shown and described.

2. The combination, with a draw-head provided with a bumper fixed longitudinally at one side, an opposing draw-head, a springactuated bumper held to slide at one side of the latter draw-head, and a dog pivoted upon the spring-actuated bumper, of a lift-bar pivoted below the said spring-actuated bumper, provided with a crank-arm at one end align ing the said dog, and a member integral with the other end projecting transversely in front of the draw-head below the same, substantially as shown and described.

3. The combination, with a draw-head, a spring-actuated bumper held to slide at one side of the draw-head, a dog pivoted upon said bumper, a lift-bar pivoted to the draw-head below the bumper, provided with a crank-arm at one end aligning the said dog, and a'member integral with the other end projecting transversely in front of the draw-head, of an angular spring-actuated pivoted pin-bar extending partially over the draw-head,provided with a crank-arm at its pivotal end, a similar opposing and aligning fixed pin-bar, a pin held between the said pin-bars,having a conical head, means for manipulating the said pin, and the bumper, substantially as shown and described.

4. The combination, with a draw-head provided with a bumper fixed longitudinally at one side, an opposing draw-head, a springactuated bumper held to slide at one side of the latter drawhead, and a dog pivoted upon said spring-actuated bumper, of an angular spring actuated pivoted pin bar extending I partially over the draw-head, provided with a crank-arm at its pivotal end, a similar opposing and aligning fixed pin-bar, a pin adapted to be held between said pin-bars,having a coni cal head, and means for raising the pin, substantially as shown and described.
